Want to hire NAS expert

I have been very happy with computer audio, my Aurender N100SSD and Synology NAS  until Comcast rebooted my modem and now everything is all screwed up. I would like to have someone come to the house and get this set up again for me. The dealer who set it up originally has lost his smart people so no help there apparently. I live in the east side of St. Paul MN. Would appreciate some help. Will pay well. Send me a note or some advice. Would be greatly appreciated.
